during the last 14 days. MAOIs are used in the treatment of depression (see ‘Taking other
medicines’).
if you have a tendency to abuse medicines or if you are dependent on medicines, as Yantil SR may
lead to addiction. In this case you should only take these tablets for short periods of time and under
strict medical supervision.

If any of the above applies to you, talk to your doctor before you take this medicine.

Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including
medicines obtained without a prescription. Your doctor will tell you which medicines are safe to take with
Yantil SR.
 Do not take Yantil SR with monoamine oxidase inhibitors (MAOIs – certain medicines for the
treatment of depression). Tell your doctor if you are taking a MAOI or have taken a MAOI during
the last 14 days.
 Your breathing may become dangerously slow or shallow (respiratory depression) if you are taking
certain sleeping pills or tranquilizers (e.g. barbiturates, benzodiazepines), pain relievers such as
morphine and codeine (also as cough medicine) in combination with Yantil SR. If this happens tell
your doctor.
 Your consciousness may be decreased, you may feel drowsier or feel you might faint, if you take
Yantil SR with sedatives (such as benzodiazepines), antipsychotics (medicines that affect the state of
mind or emotions), H1-antihistamines, opioids or alcohol. If this happens tell your doctor.
 If you are taking a type of medicine that affects serotonin levels (e.g. certain medicines to treat
depression), speak to your doctor before taking Yantil SR as there have been cases of “serotonin
syndrome”. Serotonin syndrome is a rare, but life-threatening condition. The signs include
confusion, restlessness, fever, sweating, uncoordinated movement of arms, legs or eyes,
uncontrollable jerking of muscles, muscle twitches and diarrhoea. Your doctor can advise you on
this.
 Yantil SR may not work as well if taken with opioid like medicines (e.g. those containing nalbuphine
or buprenorphine). Tell your doctor if you are currently being treated with one of these medicines.
 Taking Yantil SR with products (e.g. rifampicin, phenobarbital or St John’s Wort) that affect the
enzymes required to remove Yantil SR from the body, may affect how well Yantil SR works or may
cause side effects. The effects may occur especially when the other medication is started or stopped.
Please keep your doctor informed about all medicines you are taking.

Taking Yantil SR with food and drink

increased. You can take Yantil SR with or without food.

drive, use tools or machinery.
Any such effects are more likely to occur when you start taking Yantil SR, if the dose of Yantil SR is
changed, or if you are drinking alcohol or taking tranquilizers.
Please ask your doctor before driving a car or using machinery.

If you stop taking Yantil SR
If you interrupt or stop treatment too soon, your pain is likely to return. If you wish to stop treatment, please
tell your doctor first before stopping treatment.
Generally there will be no withdrawal effects when treatment is stopped. However, on uncommon occasions,
people who have been taking the tablets for some time may feel unwell if they suddenly stop taking them.

gradual reduction of the dose.
If you have any further questions on the use of this product, ask your doctor or pharmacist.

POSSIBLE SIDE EFFECTS

Like all medicines, Yantil SR can cause side effects, although not everybody gets them.
4

Important side effects or symptoms to look out for and what to do if you are affected:
 This medicine may cause allergic reactions (uncommon). Symptoms may be wheeziness, difficulty
breathing, swelling of the eyelids, face or lips, or rash or itching, which may cover your whole body.
 Another serious side effect is a condition where you breathe more slowly or weakly than expected
(rare). It mostly occurs in elderly and weak patients.
If you are affected by these important side effects contact a doctor immediately.

Rare side effects (affect less than 1 in 1,000 patients
 addiction
 thinking abnormal, epileptic fits, near fainting, uncoordinated, feeling drunk or relaxed
 delayed emptying of the stomach (impaired gastric emptying).
In general, the likelihood of having suicidal thoughts and behaviour is increased in patients suffering from
chronic pain. In addition, certain medicines for the treatment of depression (which have an impact on the
neurotransmitter system in the brain) may increase this risk, especially at the beginning of treatment.

Although tapentadol also affects neurotransmitters, data from human use of tapentadol do not provide
evidence for an increased risk.
If any of the side effects gets serious, or if you notice any side effects not listed in this leaflet, please tell your
doctor or pharmacist.
